How to repair a Makita GA4540R grinder, that is sparking and smoking.

Normaly when you see a blue flash from a motor, it's the armature. But in this case it was flashing from the top of the tool. Meaning it was a faulty field.
How the field shorted out like this, I'm not sure. But I'm amazed it was also still running at all, with the amount of damaged it had done.
